Posteromedial elbow dislocation with associated lateral humeral condyle fracture in a child: a rare case report and literature review

TL;DR

A rare case of a child's elbow dislocation with a fracture is reported, emphasizing the need for timely diagnosis and treatment.

Contribution

This case report highlights a rare pediatric elbow injury pattern and its successful management.

Findings

Posteromedial elbow dislocation with lateral humeral condyle fracture occurred in an 8-year-old boy.

Closed reduction and Kirschner wires successfully treated the injury, leading to full recovery.

The case underscores the importance of recognizing rare pediatric elbow injuries for proper treatment.

Abstract

Elbow dislocations are rare in children, comprising 3%–6% of pediatric elbow injuries, with posteromedial dislocations being particularly uncommon. We describe an 8-year-old boy who sustained a posteromedial elbow dislocation with an associated displaced lateral humeral condyle fracture after a fall. Although closed reduction restored joint alignment, the condylar fragment remained displaced and required fixation with two Kirschner wires. At 6 weeks, radiographs confirmed union, and the wires were removed. By 6 months, the patient had regained full, painless motion with a normal carrying angle and no growth disturbance. This rare injury pattern may be overlooked due to overlapping ossification centers, highlighting the importance of prompt diagnosis and appropriate surgical management.
